>Or do you want someone who's going to stick around a bit longer, on the basis that much of the value of someone in a job is actually domain knowledge specific to the business and the code, rather than transferrable skills? Do the incentive structures at your company match this? If they do, thats great, but I've worked at places who don't even give raises that beat inflation and still wonder why people leave within 1-3 years. Typically what I've seen of job hopping, is more often than not their previous employer simply didn't have a proper incentive structure to keep a good engineer around very long. Alot of people leave when they realize they'll never get more than a 3-4% raise, for example. If you desire employees to stay around for awhile and really learn the product and business deeply, it needs to be incentivized properly
